CLEVIS.

SPECIFICATION forming part of Letters Patent N0. 781,696, dated February 7', 1905.

Application filed September 24, 1904. Serial No. 225,812.

To r /[]l 0/11 it may volt/Writ.

Be it known that HAnRYP. THOMAS, a citizen of the United States, residing at Akron, in the county of Erie and State of New York, have invented a new and useful Olevis, of which the following is a specification.

This invention relates to the clevises of plows, cultivator-s, and similar implements, and has for its objectto produceasimply-construeted and easily-applied device of this character wherelrv the doubletree, swingletrec, or draft-beam members are prevented from sagging or dropping to the ground when the draft strains are removed, while at the same time retaining all the necessary flexibility of movement and ability to adjust the same as required.

With these and other objects in view, which will appear as the nature of the invention is better understood, the same consistsin certain novel features of 'construction, as hereinafter fully described and claimed.

in the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters, is ill ustrated the preferred form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in the shape, proportions, and general assemblage of the parts may be resorted to without departing from the principle of the invention or sacrificing any of its advantages.

in the drawings thus employed, Figure 1 is aside elevation of the improved device applied. Fig. 2 is a plan view of the same. Fig. 3 is a perspective view of certain members of the improved device disconnected, and Fig. is a side elevation of a modified form of clevis.

The improved device may be applied with slight and unimportant modifications to any of the various forms of draft appliance employed upon plows, cultivator-s, and similar implements, and for the purpose of illustration the device is shown in Figs. 1 and 2 as applied to an ordinary steel-beam clevis and in Fig. l to an ordinary wood-beam clevis.

The improved device comprises a stock 10, having spaced cars 11 12 and a depending shoulder 13 and a head member 11, pivoted, as at 15, between the cars 11, said head memher being provided with a depending shoulder 16, adapted to bear against the shoulder 13 of the member 10. By this means the member it is limited in movement in one direction relative to the member 10, but free toswing in the opposite direction, as will be. obvious. The' rear end of the member 10 is provided with an oblong stud 17, adapted to enter a similarly-shapcd aperture in the hub 18 of a clip 19, the latter being attached, as by a pin or bolt 20, to the horizontal member 21 of the plow-clevis. The forward end of the member 1% is provided with a stud 22, upon which a clip 23 is swiveled, said clip serving to support the doubletrce or draft-beam, a portion of which is represented at 24, as by a pivotpin 25. The studs lTand 22am screw-threaded at their free ends to receive binding-nuts 26 27, respectively. The clevis member 21 is formed with spaced arms 28 29, extending rearwardly and pivoted, as by bolt 30, to the plow-beam 31 and likewise to the spaced clevis members 32 33, the clevis member 21 being adjustably connected to the clevis members 32 33 by the pin 3; in the ordinary manner. By this arrangement it will be obvious that the clip 19, while free to swing laterally upon the member 21, cannot move vertically, and the member 10, being rigidly connected to member 21 by the oblong or square stud 17 and nut 26, is likewise. held from vertical movement, but free to swing laterally with the clip 19. It will also be obvious that the evener-beam 24:, while free to swing horizontally upon its pivot 25 and to rotate vertically upon the pivot 22 and also to swing upward upon the pivot 15, cannot move downward beyond a certain degree, because of the limitations caused by the coacting shoulders 13 16. By this means the evcner-beam, while free to move in all necessary directions, cannot drop down upon the heels of the draft-animals when the draft strains are removed from any cause. Thus when stopping the plow or when backing or turning the evcncrs will be main-- tained in position and prevented from falling and annoying the horses or driver.

W hen applied to a wood plow-beam 35, as in Fig. 4, a clevis of slightly-modified form will be employed, said clevis consisting of a pair of spaced arms 36 37, secured, as by pins or bolts 38 39, to the beam and provided with a horizontal lug 40, adapted to engage the clip-19, as by the pin 20. it being necessary, as before stated, to hold the clip 19 from Vertical movement, while leaving it free to swing horizontally.

While 1 have shown two forms of plowclevises to illustrate the application of the invention, it willbe understood that I do not wish to be limited in any manner thereby, as the clevis or other coupling means between the clip 19 and the plow-beam is not a part of my invention, and the improved device may be coupled to the plow-beam by any suitable means which will permit it to operate as above described.

Having thus described the invention, what is claimed is 1. In a clevis for plows and the like, a stock havingmeans for attachment to the draftbeam for swinging horizontally thereon and provided with spaced vertical ears and a depending stop-shoulder, and a carrier member having means for attachment to the evenerbeam for rotation thereon and pivoted to swing between said spaced ears and provided with a depending shoulder adapted to bear against the stop-shoulder of said stock member.

2. In a clevis for plows and the like, a stock member having at one end spaced vertical ears and a degending shoulder and at the opposite end thereof a rectangular stud provided with a threaded extension, a clip provided with spaced arms for horizontal swinging connection to the draft-beam and having anapertured hub adapted to engage said rectangular stud and held thereon by a nut engaging the threaded extension, a carrier member having-at one end a threaded stud and pivoted at the other end between the ears of said stock and provided with a depending lug adapted to bear against the lug on said stock, and a clip mounted for rotation upon said threaded stud and held thereon by a nut and provided with spaced arms for embracing the evener-beam and pivoted thereto.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

HARRY P. THOMAS.
